intervals feebly convex; hind tarsi slender, fully two-thirds as long 

 as the tibiae, the first joint rather longer than the next two combined 

 but not quite as long as the fifth. Length (cf) 3.3 mm.; width i.o 

 mm. Indiana, -Levette. [Badister and subsequently JE,pus testa-

The form of the prothorax reproduces very nearly that of the 

 genus Anthracus Mots., but the chief peculiarities of the species 

 are the triple elytral series of setigerous punctures and the long and 

 conspicuously heavy antenna?; it seems to be but seldom taken and 

 may actually be rare. 



Goniolophus n. gen. 



The limited number of small species forming this genus are 

 evidently related to Philodes and Anthracus by the form of the 

 prothorax, but differ from the former in having only a single series 

 of fewer punctures on each elytron; in Anthracus there is only the 

 usual single discal puncture. The emargination of the mentum 

 is as in Philodes, but the labial palpi have the second joint about 

 as long as the third, the latter more gradually and less finely acu- 

 minate apically. The ligula is very narrow, parallel and the para- 

 glossae are unattached for a considerable distance from its apex; 

 they are elongate and obtuse at tip, nearly as in Philodes and extend 

 well beyond the tip of the ligula, which has the usual two very 

 long setae; the inner lobe of the maxilla is broadly arcuate and much 

 extended at apex, the inner fringe subspinuliform, the last joint 

 of the outer lobe very long, gradually and moderately inflated 

 basally, thence drawn out and very slender for more than half the 

 entire length distally. The neck is short, the eyes large and very 

 prominent, the frontal foveae oblique but not attaining the eyes 

 and the mandibles are short, in large part concealed in repose. The 

 antennae are slender, the first two joints virtually glabrous, the 

 third pubescent nearly like the fourth. The scutellar stria is long 

 and strong and the lateral line of foveae is distinctly interrupted 

 medially. The anterior tarsi in the male are nearly as in Philodes, 

 but rather less strongly dilated, the laterally obliquely angulate 

 joints 1-4 each having two larger, very long, somewhat trans- 

 versely crumpled, internally serrulate, hyaline plates, which are 

 obliquely semi-erect; the fifth joint is as long as the preceding three
